4NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 576,380, dated February 2, 1897.

Application filed June 29, 1896.

To all whom, it may concer/b:

Be it known that I, DAVID B SAUNDEES, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Non-Refillable Bottles; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to nonrefillable bottles.

My Objectis to provide a non-relillable bottle of simple, cheap, and improved construction, which can be quickly and easily sealed, and while so sealed the contents of the bottle can be removed at any time without difficulty, and yet, owing to its peculiar construction, it will be impossible to refill the bottle without detection.

A further object is to provide an improved non-relillable bottle having a 4peculiar and novel arrangement of valves and parts and which can be kept sealed for an indefinite period of time, but will be capable of quick unsealing, so that upon tilting the bottle the valve will operate and the fluid contents allowed to iiow from the bottle, but owing to the peculiar construction of my improved bottle it will be impossible for the same to be refilled.

Having these objects in view, my invention consists of a non-reillable bottle comprising certain improved and'novel features and combinations of parts, appearing more fullyin the following description and appended claim and in the accompanying drawings, in which- Figure l is a sectional elevation of my improved bottle as sealed, and Fig. 2 a crosson the line c of the preceding figure. I

A designates the bottle, and B the neck, which is made in two sections 1 and 2. The section l is blown integral with the neck and extends down into the bottle somewhat and has a flat lower face 3. This section is provided with a central circular opening 4, which extends therethrough. l

The numeral 5 designates upwardly-extending arms, which are separated by the passage 4 and are formed integral with the Serial No. 5 97,282. (No model.)

section. The upper ends of these arms are squared off, and as many arms can be-employed as desirable. It is necessary that these arms be provided or else a space left in the neck of the bottle Vat this point, so that the fiuid will have free passage out through the neck after it has gone through my improved auxiliary neck, which will be described hereinafter. The arms are formed integral with section l, and owing to their thickness an annular shoulder 7 is provided. The upper section of the main neck is blown integral with the lower section thereof, but it is quite thin, as shown, so that an annular space 7 will be left between it and the arms just described. It willbe observed that this upper section extends considerably higher than the upper ends of the arms, so that after the auxiliary neck has been placed in position there will be ample room for a removable cork or stopper, as will appear more fully later on.

My improved auxiliary neck is shown at C.

This neck can beconstructed of any desired v material, glass being preferred, although I sometimes employ metal, which is by preference coated with aluminium.

The numeral Sdesignates a cylindrical tube, which is of such size that it will snugly iit within passage 4. This tube is provided near its lower: end with an inner annular shouldei` 9, which, when the auxiliary neck is constructed of glass, is blown integral with the latter. Should metal be employed in connectionwith the neck, this iiange may be constructed of wire suitably connected to the tube. The upper head of the tube is formed with a solid head l0, which is provided with a depending annular fiange or hood ll, having vertical openings 1l', which are in alinement with the outlet-grooves l1 in the upper section 2 of the neck. It will be observed that the tube is provided with a vent or opening l2, and the hood just described extends down somewhat below this vent.

should be located at such a distance from the head that there will be ample room in the tube between it and the head to accommodate a ball-valve, which snugly fits the tube and is designated by the numeral 13. It will be observed that the head is somewhat concave at the end of the tube, as shown at 14, so that The vent 9 D IOO it will constitute a pocket to receive the ballvalve. lf desirable, this pocket could be faced or plugged with cork, so that the impact of the valve with it will be suitably cushioned, but it is not necessary. The ball-valve has free play within the tube and the annular shoulder 9 and the concave pocket, and when it has passed the Vent or opening 12 the iluid is allowed to make its exit.

The numerals 15 designate a series of springs, which have inclined converging portions 16, shoulders 17, and straight portions 1S, which latter are adapted for connection to t-he extreme end of the tube 8 in any preferred manner. Although in the present instance l have shown two of these springs, yet it is obvious that as many could be employed as found desirable, while on the other hand it is only necessary that one be used.

After the bottle has been lled it is sealed in the following manner: The springs on the endof the auxiliary tube areinserted between arms 5 and 6 and the auxiliary neck pushed down. The springs are readily compressed when inserted in the passage of the main neck, but when the lower face 3 of the latter is reached the springs become freed and they spring outward, so that their shoulders 17 engage with the face 3 and the auxiliary neck is irmly locked in position, so that it cannot be removed. When thus placed, the hood 11 lies in the annular space 7'and the head rests upon the upper ends of the arms 5.

vIt is necessary that the auxiliary neck be so manipulated when being placed in position that the opening in the tube will face one of the open spaces between the arms 5; otherwise-the fluid could not be allowed to flow out. The vheight of the upper section of the main neck is such that ample space is left for the insert-ion of a cork stopper 19, which is preferably placed in position so that the contents of the bottle will not be lost should the latter accidentally become tilted. When it is desirable to obtain the contents of the bottle,

this is accomplished by removing cork 19.

The bottle is then tilted, and by the ei'ect of gravity andthe weight of the fluid the ballvalve rolls down the tube, so that the vent therein is passed and the fluid is allowed to go out through the vent and be poured into the receptacle. Immediately upon restoring the bottle to upright position the ball-valve reseats itself upon the inner annular shoulder of the tube, so that it is impossible for any fluid to be forced into the bottle. The only way that the auxiliary neck can be removed is by breaking the bottle itself, so that ample protection is afforded against the refilling of the bottle.

It is obvious that many slight and immaterial changes of construction might be resorted to without detracting from any of the advantages of my invention; and it is to be understood, therefore, that I do not limit myself to the precise construction herein shown and described, but consider that I am entitled to all such variations as come within the spirit and scope of the invention.

Having now described my invention, what I claim as new, and desire to'secure by Letters Patent, isn

In a non-reiillable bottle, the combination with a main neck comprisinga lowerrsec'tion having a shoulder at its lower end, and apa-ssage extending therethrough, and arms extending up from said section, and an upper section of the neck separated lfrom the arms by an annular face, of an auxiliary neck comprising a tube vhaving a vent, an inner shoulder and a head provided with'an annular hood which protects the vent, a ball-valve rollable in the tube, and locking-sprin gs connected to the lower end of the tube, said tube being adapted for reception in the passage of the main neck and the'spring to lock against the shoulder of the latter, and the hood lying in the space between the opening and the upper section of the main neck, and a cork or stopper located on the main neck above the head of the tube.

In testimony whereof l 'have signed this specification in the presence of two subscribing witnesses.
